This popular vitamin, especially in high doses, protects the from the harmful effects of fine particulate matter. These pollutants, known as PM2.5, lead to numerous health issues, including asthma and lung cancer.
Researchers from the University of Technology Sydney (UTS) conducted a series of experiments on mice and human tissue grown in the lab. The team aimed to investigate the protective effects of vitamin C on tissues exposed to PM2.5 particles. Ultimately, the scientists discovered that this vitamin shields cells from some of the major damage typically inflicted on the lungs by air pollution.
What Did the Scientists Discover?
C has long been known for its antioxidant properties. Thus, it’s no surprise that researchers sought to test its protective action against airborne pollutants.
The team found that vitamin C reduced the loss of mitochondrial “power stations” in cells, decreased harmful inflammation, and prevented cell damage caused by oxidative stress from unstable, reactive molecules.
“Antioxidant vitamin C supplements proved effective in mitigating the adverse effects of PM2.5, so they can be recommended for high-risk individuals,” the researchers noted in their report.
“This study suggests that consuming the maximum allowable dose of vitamin C protects the lungs. However, it’s essential to consult a doctor to ensure you’re taking the right supplement at the correct dosage,” emphasized molecular biologist Brian Oliver, a co-author of the study.
PM2.5 particles typically arise from traffic congestion, wildfires, and dust storms, and they are extremely harmful to our health, as highlighted by Science Alert. Even low levels of air pollution from these particles can cause significant cellular disruptions. Interestingly, the level of PM2.5 pollution to which the lab rodents were exposed is comparable to levels frequently recorded in developed countries today.
“For the first time, we’re offering hope for an affordable preventive solution to a global problem affecting millions. Now we know there is no safe level of that causes lung inflammation and leads to numerous respiratory and chronic diseases, especially in the case of wildfires,” said Oliver.
The findings of the study were published in the journal Environment International.
